Inventor: SHINKAI K
IPC: H04N9/24
Filed: 1979-11-23
Abstract: In a beam index color television receiver having the screen of its color cathode ray tube provided with a repetitive pattern of a plurality of groups of different primary color phosphor elements arranged side-by-side across the image area of the screen to be scanned by a single electron beam as the latter is selectively modulated by respective color signals, index and mode set signals are provided in response to scanning by the beam of respective locations on the screen which are interspersed across the latter with distances therebetween which are non-integrally different from the pitch of the groups of color phosphor elements, and with adjacent locations corresponding to the mode set signal being spaced apart by an integral multiple of such pitch. The index signal can be provided by the scanning with the beam of index elements at the corresponding locations on the screen which emit light or other radiant energy, while the mode set signal may be provided in response to the absence of the index elements at the respective locations or to the presence, at the latter locations, of mode set elements which emit distinctive radiations when scanned by the beam. In any case, a gate pulse generator is responsive to the index signal to provide sequentially repeated gating signals by which the color signals are gated to selectively modulate the electron beam, and the phase and sequence of the gating signals are controlled in response to the mode set signal for ensuring that, as the beam scans each color phosphor element, the beam is modulated by the corresponding color signal.

Title: EM radiation refraction measurement - varying distance between two sources until one beam bisects other at second measurement point
Inventor: MARTENSSON STIG-GORAN
IPC: G01S3/78
Filed: 1981-07-08
Abstract: From a radiation source (S) light is transmitted and picked up by an observer (O) who has a theodolite (T) for measurement of the angle (V) formed by the radiation (SO) with the horizontal plane. This angle can then be used to determine the horizontal distance (L) between radiation source and observer. Due to air density variations between source and observer, refraction of the light beams occurs. This means that the measured angle (V) invariably has an additional value which requires accurate determination to arrive at the height angle. Thus, two sources of e.m. radiation with different frequencies are located one above the other at the one measurement point. The distance between them is varied until a beam from one of them bisects one from the other at the second measurement point, and this distance is then measured as an extent of dispersion between the beams.

Abstract: A PCM digital signal is provided with double-interleaving and error-correction encoding to protect against errors occurring during transmission, which can be carried out by magnetic recording and reproducing. The PCM signal is processed as error correcting blocks of several data word sequences and an associated error correction word sequence, and the double-interleaved sequences are then transmitted as transmission blocks. Up to one erroneous word in each error correction block can be corrected by using the error correction word sequence. Any uncorrectable word can be compensated by substituting a synthetic word interpolated from immediately preceding and following data words known to be correct. The distance between successive data words is made as great as possible so that a long burst error is unlikely to affect the ability to compensate uncorrectable errors. To achieve this, alternate words of the PCM signal are distributed to odd and even groups of sequences, and the interleaving is carried out by imparting different delay times to the respective sequences such that the greatest delay time imparted to the odd sequences is less than the shortest delay time imparted to the even sequences. The error correction word sequence is provided with a delay time intermediate the greatest delay time of the odd sequences and the shortest delay time of the even sequences.

Abstract: A process and an apparatus are described for the continuous rectification with minimum consumption of energy and material of, in particular, mixtures having a plurality and a multiplicity of substances, and temperature-sensitive substances, preferably having relatively low volatility. The invention is characterised in that the majority of the reflux resulting from the circulation of the liquid amounts present in the column system is delivered at the column head and as a result the ratio of the reflux amounts to be evaporated and distillate amounts corresponds to the values of the minimum reflux ratio or even smaller values. As a result of partial condensation at inner and outer mass transfer surfaces and, depending on the position of the cut and the partial pressure differences (alpha value), a one to many-fold reboiling of the partial condensates at the inner surfaces, a low pressure drop and a small apparatus height - the latter decreases with decreasing feed concentration at constant high end concentration - are achieved. The invention can be used in particular for vacuum distillations for further processing of thermally sensitive mixtures containing a plurality and a multiplicity of substances.

Abstract: The present invention relates to a method which eliminates centrifugation and decantation steps, to be performed in an automatic manner for carrying out specific binding assay tests, wherein liquid and solid phases are present. According to the invention, use is made of a specially designed device, consisting of a mixing reservoir into which is fitted snugly a mixer separator having a channel in the vertical axis of the mixer-separator. A rack holding a number of said mixing reservoirs containing the incubated reagents and analytes, capped with the mixer separators, is placed into a press-device designed to perform at a controlled rate a downward movement. The mixer separators are pushed downwards into the mixing reservoirs at a chosen rate for a preselected distance to complete the mass transport and separation operations. The separation devices are removed and either one of the separated phases can be measured in the desired analytical instrument for a quantitative or qualitative determination. The results obtained according to the present invention compare very favorably with those determined by other methods requiring centrifugation and/or decantation in the assay protocol.

Abstract: Method of conferring load and deformation stability on railway tracks by means of partially prestressed concrete structures, for instance concrete sleepers. The prestressing forces in the tendons during casting and curing may amount to one half of the value for full prestressing. In conjunction with both normal loads and sporadically occurring overloads, the magnitudes of the deformations in the sleepers will be regulated by the stiffness of the sleepers, the modulus of subgrade reaction of the ballast, and the ability of the rails to transmit force. Owing to enhanced deformability of the concrete sleepers in consequence of the reduced prestressing force in the tendons, considerable load energy can be absorbed without the occurrence of permanent damage. The structure as a whole is given such properties that the sleepers exhibit only elastic deformations, and that the cracks which occur in the concrete cross section in tension are completely closed after the load has ceased to act.

Title: Encapsulating silicon ceramic articles prior to hot isostatic pressing - by coating with glass-forming materials and heating in a vacuum
Inventor: GRUNKE R
IPC: C04B35/58
Filed: 1983-12-14
Abstract: Ceramic moulded articles of Si3N4, SiC etc. are compressed until free of pores within an evacuated capsule of high temp. resistant glass. The glass starting materials are deposited on the ceramic in a non-vitrified state and they are heated to their reaction temp. until the glass layer has formed an adhesive capsule around the moulded article. In one method Al is vaporised onto porous reaction-sintered silicon nitride which in a first heat treatment step is held at atmospheric pressure for a long time at a relatively low temp. to convert the metallic Al to Al2O3. The silicon nitride is then subjected to a second heat treatment for a short time in vacuo at a high temp. to convert Al2O3 and SiO2 to the glass. Simultaneous encapsulation and evacuation of a porous compact is simply produced prior to hot isostatic pressing.
